Failover & redundancy setup...

I work for a wireless ISP. We are in the process of converting our
network to use DHCP and honestly ISC DHCP works great.
We are setting up a redundant server which I originally planned to use
anycast to provide easy redundancy. However for failover it requires a
split or hba command to decide who answers the query which means both
have to receive it.
This is not much of a problem it is just that our 2 server farms are
relatively far apart and i was planning to route requests to the closest
one to minimize latency and only failover to the further server if the
closer one died.
I am currently using 3.1.1 (latest stable in gentoo's package system)
and thus far searching through the change logs this behavior hasn't
Thanks in advance for any help provided.
